SDT51822B has been designed by Sigma Delta Technologies for easy prototyping of IoT devices. This tiny, low-cost BLE 4.0 enabled board is equipped with 0.25°C resolution temperature sensor, making it suitable for connectivity devices. The nRF51822-QFAC MCU features 32bit Arm® Cortex® - M0 core. In addition, there is operating power selection option of 1.8V for low power and 3.3V for high performance. The board provides pheripherals of one UART interface, two SPI interfaces, two I²C interfaces, three GPIO pins and four 8/9/10-Bit ADCs.

At Sigma Delta Technologies Inc., the SDT Board is a board with a target MCU which can be connected with the DAP Station through micro-connectors. SDT Boards are used with the DAP Station and Interface for easy programming and debugging.

SDT Boards can not be programmed independently, so please refer to the below links for DAP Station and Interface.

Use the USB lead to connect your mbed to a PC. The status light will come on, indicating it has power. After a few seconds of activity, the PC will recognise the mbed Microcontroller as a standard USB drive.

Windows

From a host PC to communicate with mbed you will need a terminal application. This allows the mbed Microcontroller to print to your PC screen, and for you to send characters back to your mbed.

Terminals - Using Terminal applications to communicate between the Host PC and the mbed Micrcontroller

Some terminal programs (e.g. TeraTerm) list the available serial ports by name. However, if you do need to know the identity of the serial port so that you can attach a terminal or an application to it:

Windows

Mac

Linux

Find the identity of the COM port by opening ''Device Manager''. To do this navigate ''Start -> Control Panel -> System -> Hardware -> Device Manager''.

To find the device name under Mac OS X, use the command ''ls /dev/tty.usbmodem*''

To find the device name under Linux, use the command ''ls /dev/ttyACM*''
